Determine the t-value for a Two-Sample t-Test: Using the data from the previous question with an SE of 2.55, calculate the t-value to test the difference in recovery times between the two groups. Round to two decimal places, and assume t value is positive. Formula: t = (Mean₁ − Mean₂) / SE

Determine the Effect Size for a Difference in Means: In a study comparing sedation times, Group A has a mean sedation time of 40 minutes (SD = 8, n = 30), while Group B has a mean sedation time of 50 minutes (SD = 8, n = 30). Calculate Cohen’s d as a measure of effect size. Round to two decimal places. Cohen’s d = (Mean₁ − Mean₂) ÷ SD_pooled

Calculate the Relative Risk Reduction (RRR): If the Risk Ratio for an anesthetic intervention is 0.7, calculate the RRR. Convert to a percent. Enter a whole number only. Formula: RRR = (1 − Risk Ratio) × 100

Calculate the Standard Error (SE) of the Difference in Proportion for Complications: In a comparison of two anesthetics, 30% of patients in Group A experienced complications (n=100), while 20% in Group B did (n=100). Calculate the SE for the difference in proportion. Round to the thousandths place. Formula: SE = √
